This invention relatestoa fixed position support or anchorage-construction' r Thechief object of this invention isto' I provide a readily mounted, detachable,.substantially fixed mounting arrangement for asupporting 01".. supported member, and herein the same is shown adapted for headlamp tie bar use. I j v The chief feature ofthe invention consists in, positioning upon 7 a supporting. member, such as a headlamp casing, and in an aperture thereof, a supporting ferrule and associating. therewith a locking spring, the

.. ferrule extending through the-aperture and bearing upon one wall thereof, and the spriugbearing upon the opposite wall.

The full nature of the invention will be more fully understood from the accompanying drawings and the'following description and claims: I

. In the drawingsFig. 1 is a from View of a conventional automobile provided with a pair of independently .mou'nted headlamps and a tie barconnecting the same. Fig. 2 is an enlarged transverse sectional view through one of the headlamps and illus trates the invention associated. therewith and supportingtie bar construction. Fig.3 is

an elevational' viewjofthe. aperture in the headlamp casin Fig; 4; is a longitudinal sectional view through the ferrule. Fig. 5 is :a longitudinal central sectionthrough the bushing. Fig. 6 is a front VlBW- of the locking spring. 1 Fig. isa rear view of the ferrule and bushing. p

In the drawings lO-indicates an automobile including the fenders 11 from which extend brackets' l2 each supporting a headflamp 13, each connected byfa, tie bar 1a to,

prevent'lateral play therebetween and re duce vibration-to a minimum. .This tie bar arrangement is old in-the art but the casing mounting thereof is not. i

The headlamp 13 includes a casing .15 which is arranged asat 16 and 17to form a circular flat plateportion' 18 which is apertured in substantially circular form as at 19, except that there is provided a pair of diametrically positioned inwardly extendlng tongues 20. A [ferrule is telescopincludes an annular projecting bead or I flange portion 30.- Extending through-the bushing is an elliptical bore or opening 31.. which is adapted to register with the opening-26 in the ferrule. Relative longitudinal movement between the bushing and ferrulewhen the former is mounted therein is prevented by the flange 30 seating in the annular groove forming portion 1 21. The rod llhas across section substantially that of the bore 31 and the opening 26. I The rod extends through "the same and may project therefrom; see Fig. 2.

The locking spring 4. .0 is nular and includes a-pair of inwardly directed tongues a1. The spring is preferably curved in edge elevation; see; Fig. 2.

The mount for the tie bar 14 is mounted as foll0ws:.The bushing is mounted inthe ferrule and both are passedthrough the aperture 19 of the casing untilthe flange portionv 21 engages one face of the .plate 18.

This movement is permitted by the tongues, 20 of the casing being slidably receivable by. an elongated slot 3 5' in the tubular portion 22'0f the ferrule and'said slot extends substantially the full length of said tubular portion. A pair of said slots is. provided Yer rfonooimnnsvirmn, rnniana, ASSIGNOR T0 .I'I TDIA'NA LAMrooRy substantially 3.3 i

and the same arepositioned' diametrically opposite each other; The spring FLO is then telescoped upon the ferrule upon the opposite side of the casing; The tongues ell of the spring are also receivable by fthe elongated slots 35. However, to maintain said spring in holding and locking rela tion each slot 35 includes a lateral extension.

36 and the throat thereof is closed by a;

projection 37. The same constitutes anQL- shaped extension. This L-shaped extension of the slot is positioned relatively .close to the bead or enlargement 21 upon the ferrule. The result is a bayonet slot type lock for the spring whereby theentire mount is mounted upon the casing in predetermined relation. i

' The invention claimed is:

the tie bar comprising a supporting. plate portion of thelamp having itClIC'LllEtl aperture therein a c lindrical ferrule rece vable by said'aperture and including a plate engaging flange, said ferrule and plate having atongue and slot connectionpreventing rela- 'tivegrotation therebetween, and a circularly apertured and curved ferrule encircling spring having a complementary portion: for

tongue and slotfconnection with, said ferrule andwitli the. first 'mentioned tongue and slot connecting portion thereof, said spring being directed toward the opposite face of the flange engaged plate portion for clampingly retaining the ferrule thereon.

7 support member comprising a. supporting 2. A detachable cushion anchorage for a support membercoinprising ft'SllppOltlllg plate having a circular aperture therein, acylindrical ferrule receivable by sa d aperture and including a plate engagingflange', said ferrule and plate having a tongue'and slot connection preventing relative rotation therebetween, a circularly apertured and curved ferrule encircling spring having a complementary portion for tongue and slot connection with said ferrule and with the firstmeiitioned tongue and slot connecting portion thereof, said-spring being directed towardthe opposite'face ofthe flange engaged plate for clampingly retaining the ferrule thereon, and a cushion bushing positioned in said ferrule for'cushioning the 7 support member and ferrule connection.

8. A detachable cushion anchorage fora plate having a circular aperture therein, a

cylindrical ferrule receivable by said aperture and including a platerengaging flange,

said ferrule and plate having a tongue andslot connection preventing relative rotation tlierebetween, a circularly apertur'ed and curved ferrule encircling spring having a complementary portion for tongueand slot connection with said ferrule and with the ,first mentioned tongue and slot connecting -port on thereof, said spring being directed toward the opposite face of the flange engagedplate for clainpingly retaining the ferrule thereon,,and a cushion bushing positioned in said ferrule for cushioning the support memberand ferrule connection, said bushing and said ferrulev having comple- 1. ;The combination with a'pair ofhead-i lamps and 'a tie bar-therebetween, of a detachable anchorage between each lamp and inentary portions for locking the foriner I within the latter.
